Ultratac S20

BLightSam:

Could somebody make a comparison with Sofirn SP32A?
Page Not Found - Aliexpress.com

I have the SP32A only, I think this Ultratac S20 is relatively new, only one review on amazon and no reviews anywhere else I could find.

.

Differences from what I see already:

Sofirn is longer length. (122.7mm vs 100mm)

Sofirn has NW emitter (CCT Range): 5350K-5700K (Neural White) Apparently Ultratac is CW.

Sofirn has 2 mode groups, regular and ramping, Ultratac only one group, no ramping.

Sofirn in regular group has 5 levels (LL-L-M-H-Turbo) Ultratac only 3 levels (L-M-H) Both lights have Strobe.

Sofirn has quick access to turbo (double click from OFF or any mode)

Sofirn has metal switch, Ultratac appears a rubber cap.

Sofirn is brighter and has the latest Cree XP-L 2nd generation, Ultratac has older version Cree XP-L:

Sofirn:…….XP-L2………1500lm
Ultratac:… XP-L V3……1100lm

So the Sofirn is better, unless your main concern is length and you don’t mind CW tint and the lower max output.

I like just 3 modes, length is critical to me (18650 lights are on the border of pocketable), and I can replace leds myself. So that makes the S20 more interesting to me than the SP32A. Critical as well is direct access to low mode from off, that still has to be confirmed.

Wow, sounds like you (djozz) and I have similar taste in EDC’s - direct access to low, no memory, LED swappable to our own choice, simple 3 (or maybe 4) modes, as short as possible - just add deep pocket clip availability to that list for me. I know it’s anathema, but I’m actually not carrying an EDC much anymore because I need to find something shorter than doesn’t bother me in my pocket. Phones keep getting larger which means more of a problem carrying my EDC light. I started trying to put the light in my rear pocket, but that’s not always comfortable either. I might try going to a belt clip/pouch.

@beam0,

Thanks for the “detailed” comparison despite not having much detailed info.

Brightness of 1500lm intrigues me when others in this category is about 1200 — 1000lm. (Will 300lm difference be noticeable?)

grayski74 · 2018-03-22T19:26:52.000Z

I like the look of the S20 as long as it is l-m-h and not h-m-l.

Maybe they will make an “S10”? would be good for 18350. Maybe 60mm long etc?

I’m always looking for the shortest 18650 light, that’s why I’m subscribed to this thread.

I already have the SP32A and it’s a great light but it’s long…

…However… the main reason I got the SP32A is because it legos with the Convoy / Jaxman 18350 & 18500 tubes:

106.7mm with the 18500
89.3mm with the 18350

So it’s a real gem with the shorty tubes.

.

So for this Ultratac I agree with you djozz, 3-mode is fine and I will also swap the LED, but I also need to know the UI.
One thing I would miss (if it doesn’t have) is direct access to the highest mode.

1200 to 1500, maybe not so much
1000 to 1500, it will be noticeable

BLF A6 and Zanflare F1 are supposed to be 1200 lumens (Turbo). Turns out SP32A also gives out only 1200 lumens instead of the listed 1500 lumens, according to 2 reports. So my question becomes moot.

(Thanks for others responses.)

Yeah, I though 1500lm sounded a little high for what I’m seeing, but 1200lm is quite bright. I’ve got to get a light meter, at least to do basic comparisons.

………………… S20 User Interface: ……………………

Long press for ON/OFF (memory - starts on last mode used)

Single clicks to change modes L-M-H

.

Hidden Strobe: Fast double click (from ON)

Lock out: Double click (when OFF) to activate/deactivate

I wished mode memory was never invented If I can not even remember the important things in life, why on earth should I know in what mode my flashlight was last time I switched it off?

I agree, I despise mode memory.

Instead of memory, a better solution would be having shortcuts from off to various levels, like this:

(UI of DQG Tiny 26650 III)

From OFF
–1 click to med
–2 clicks to high
–3 clicks to low
-Hold for turbo

From ON
–1 click to off
–2 click to turbo
-Hold to change modes: low-mid-high

It would be great to have a UI like DQG’s above, with programmable firmware that you could pre-set/change your desired levels for the turn on clicks.

Strange, I don’t see it listed on the home website?

I noticed that too about 10 days ago when I found out about this light.

I also find it odd that a company can design and implement a new model, all they way through production and listing it on amazon, but still not have a listing for it on their website. I’ve also noticed this same pattern with one or two other companies, can’t remember which ones ATM.

Just became aware Zebralight has this type of UI, and in the latest version the brightness levels are programmable:

Basic Operation:

One click turns on the light to High or turns off the light.
Two clicks turns on the light to Medium.
Three clicks turns on the light to the beacon-strobe mode.
Long press turns on the light to Low and then Medium and High. Release at the desired level

H1, H2, M1, M2, L1 and L2 can be programmed to any of the 12 available brightness levels

.
Under consideration are these 3:
(all are 18650, NW 4500K CRI80+)

92.5mm length:
SC64w (XHP35) SC64w 18650 XHP35 Neutral White Flashlight-SC64w

96mm length:
SC600w Mk IV HI (XHP35 HI) SC600w Mk IV HI 18650 XHP35 Neutral White High Intensity Fla
SC600w Mk IV Plus (XHP50.2) http://www.zebralight.com/SC600w-Mk-IV-Plus-18650-XHP502-Neutral-White-Flashlight_p_225.html

Of course they’re quite expensive, but I already have many lights, so at this point I could buy one Zebra in place of the next 2 or 3 budget lights.

Check out the Nitenumen “C8” EDC w/USB charging, 99mm length.

Started a thread on it today: Nitenumen compact EDC 18650 light w/USB charging - Amazon deal

moderator007 · 2018-05-22T00:29:01.000Z

I came across this ultratac s20 light today on amazon and started searching, it landed me here (my flashlight home). Has anyone purchased this light or have anymore info. I can’t find a review anywhere.

djozz · 2018-05-22T06:35:35.000Z

I haven’t, waiting for someone to do a review/impression. It is all about the user interface, if that is good I want one, if not good this flashlight is one of many I will not use and therefore not buy.

grayski74 · 2018-05-22T08:00:21.000Z

I am waiting for a review too… One that covers, as you say, the interface, and also whether there is PWM.

Also for the Nitenumen C8.

I need to know if there is PWM before I buy, and if there is, is it high enough frequency for me to not notice.

I don’t have this light yet either but i did post about the UI in post #28 above (with photo from the user manual), looks like it starts on low.
